Sendbird is a communications API platform with a 4.5/5 G2 rating from roughly 137 reviews (2026), used by over 4,000 applications including Reddit, Yahoo, Delivery Hero, and Hinge. The platform provides chat and messaging APIs that developers embed into mobile and web applications — in-app chat, push notifications, and moderation tools. Sendbird also offers a business messaging product (Sendbird for Business) for customer support with AI chatbot capabilities. The company has raised $221 million in funding.

Converge is a messaging-first inbox at $49/month flat for up to 15 agents. The key difference: Sendbird is primarily a developer API for building chat into applications; Converge is a ready-to-use messaging inbox. Sendbird targets engineering teams that build custom chat experiences; Converge targets support teams that need a plug-and-play inbox.
